particularly to provide a simple, efiicient and durable portable receptacle by means of which the contents of the receptacle may be maintained without material change of temperature for considerable periods of time.

Further,-said invention has for its object to provide a receptacle of the character specified comprising an inner receptacle, and an inclosing casing therefor which is so disposed about said inner receptacle that it is substantially free therefrom.

Further, said invention has for its object to provide a receptacle of the character specified in which the outer casing is formed of a plurality of parts so constructed and arranged relatively to each other that the same may be readily opened to permit of the insertion or removal of the inner receptacle.

Further, said invention has for its objectinclosing casing also serves to maintain said receptacle free from contact with the walls thereof.

1 To the attainment of the aforesaid objects and ends, my invention consists in the novel details of construction, and in the combination, connection and arrangement of parts hereinafter more fully described, and then pointed out in the claim.

In the accompanying drawings forming part of this specification, wherein like numerals of reference indicate like parts, Figure' 1 is a back view showing one form of vacuum bottle constructed according to and embodying my said invention; Fi 2 is a front view showing the cap ofthe inclosing casing removed therefrom; Fig. 3 is an enlarged top view of Fig. 1; Fig. 4 is an enlarged transverse section taken on the line H of Fig. 2; Fig. 5 is a side view showing the outer casing opened to disclose the manner of supporting the double-walled inner receptacle. in position therein, and Figs. 6 and 7 are respectively enlarged detail side and sectional views of the cap for closing the top of the outer casing; the latter view being taken on the line 7-7 of Fig. 6.

In said drawings 10 designates the vacuum bottle or receptacle as a whole, comprising an inner double-walled receptacle or bottle 11 of usual general construction having a Patented J i e, ieie.

tapering neck 12, and a rounded bottom 13 provided upon its underside with a centrally located depending teat or projection 1 1.

15 denotes a substantially cylindrical outer inclosing casing whose interior diameter and length are greater than the exterior diameter and length of the receptacle or bottle 11. The said inclosing casing 15 is composed of two parts or halves 16, 17 which are hinged together longitudinally along one edge, and provided along one of their free edges with a raised or overlapping portion 17 adapted to receive the free edge of the other part or half.

The casing parts or halves 16, 17 are provided adjacent to their upper ends with registering rounded shoulder portions 18, extend upwardly two.

18 from which straight, registering neck portions 19, 19 having their upper edges turned inward to form an annular lateral flange or rim 20.

Upon the outer sides of the neck portions 19, 19 are .provided outwardly extending studs 21, 21 which are adapted to be engaged by angular recesses 21 21 formed in the opposite edges of a cap 22 and adapted to be fitted upon, and inclose the combined neck portions of said casing, 15.

23 denotes a fiat curved spring having its inner end secured to the inner side of the casing half 17 about midway of its len h, and its outer end projecting beyond the rec edge of said casing portion 17 and provided with an aperture 24, adapted to receive an inwardly extending projection 25 upon the inner side of the casing half 16 when said parts 16 and 17 are brought together.

26 denotes a stud secured to the sprin 23 adjacent toits free end which stud extends through an aperture in the easwith the projection in order to open the casing 15.

27 denotes a spiral annulus arranged in the upper end of the casin 15 and contacting with the shoulder portions 18, 18 thereof, and 28 denotes a helical tapering spring supported upon the base of the casing 15 having its upper 'end bearing against the rounded lower end of the inner receptacle 11, and surrounding the projection 1.4 thereon. The spring 28 serves to yieldingly support the receptacle 11 within the casing 15 free from the bottom thereof, and at the same time maintain the shoulder of the receptacle 11. in contact with the spiral annulus,27 so as to be free from the shoulder 18 of the casing 15.

In order to removably support the annulus 27, and spring 28 in position with the I by yieldingly supporting casing 15 1 preferably provide short clips or retaining members 29, 29. However, any other suitable means may be employed to this end.

It will be noted that by means of the con-- struction herein shown and described, I am enabled to provide 'a double-walled receptacle with an inclosing casing therefor which may be readily opened to permit of the removal of said inner or double-walled receptacle for claiming or replacing the same with another. Further, it will be noted that the inner. doublewall receptacle within its outer inclosing menace casing, the danger of breaking or injuring said inner receptacle is reduced to. a minimum.

Having thus described my invention what I claim and desire to secure by Letters Patent, is:

A receptacle of the character described, comprisin an outer casing formed of two correspon ing parts, or halves, means for securing said parts or halves together, an inner, double-walled vessel disposed within said casing having a neck at its upper end extending through said casing, and aprojection at its lower end, an annular spiral spring arranged within said casing adjacent to its upper end adapted to receive the neck of said inner vessel; and a helical spring disposed in the base of saidcasing adapted to engage the base of said inner vessel, and the projection thereon whereby to hold said inner vessel in position within said outer casing free from the walls thereof, and the upper end of said inner vessel in engagement with said annular spiral spring, substantially as specified.
